The relation between body composition and spinal lordosis and kyphosis abnormalities in women

The aim of this research was to study the relation between body composition (body mass index، waist circumstance، waist hip ratio، body fat percentage) and spinal lordosis and kyphosis abnormalities in women. The study design was descriptive/correlational research. Subjects were recruited from Bachelor of science attendances passed theory test in Payam nour university. Out of 600 possible female individuals، 233 participants randomly selected to be enrolled in the study (Mean ± SD age، 27. 11 ± 6. 093 years) (Mean ± SD height، 161. 09 ± 8. 533 cm) (Mean ± SD weight، 58. 9 ± 9. 34 kg). Anthropometric measurements were carried out، firstly. Then، sub-cutaneous fat thickness on triceps، suprailiac، and quadriceps muscles measured by calipers for about three seconds and three times repetition to verify the measurement. Sub-cutaneous fat thickness percentage was calculated by Jackson/Pollack formula and spinal mouse was used to assess curvatures of the vertebral column. Data analyze was performed by SPSS، version 12. Correlation is significant at the 0. 05 level. Statically significant correlation was found between body mass index (BMI) and lordosis abnormality (P < 0. 05، R = -0. 144). Our data also showed there was not any correlation between body fat percentage، waist circumstance (WC)، and waist to hip ratio index (WHR) with lordotic curvature (P > 0. 05، R = -0. 037). Results demonstrated that BMI، body fat percentage، WC and WHR did not have any correlation with kyphosis posture (P > 0. 05). The results of this study showed that WHR، WC and body fat percentage was not significantly correlated with lordosis and kyphosis abnormalities. Although، BMI had a considerable correlation with lordosis abnormality but it did not have any correlation with kyphotic curvature.
